What we don't know is the sound specifications and the minimal latency we can get with this
Maybe good for djs who likes to listen to different thing in the headphones, and the main audio out
like I said I would only use it as a backup on stage if the audio input craps out nothing more,..latency is not an issue for this use in a pinch just to play Mp3's. I also carry two fully loaded laptops with me at all times on stage also just in case.
